FEEDING MECHANISM.

Patented. Oct. 27, 1914.

Application filed September 5, 1912. Serial No. 718,759. I

To all whom it may concern Be it known that I, CHARLES F. BENDSHAD- LER, a citizen of the United States, residing at Elgin, in the county of Union and State of Oregon, have invented new and useful Improvements in Feeding Mechanism, of which the following is a specification.

My invention relates to feeding mechanism, and particularly to a mechanism for feeding boards or shooks to box making machines. I

An object of my invention is to provide a device adjustable to accommodate the feeding of boards of various sizes.

Another object of the invention is to provide a novel and efficient means for driving the machine. 1

A further object of the invention is to pro-vide an improved form of means for maintaining the boards or shooks in feeding position upon the bed or table of the machine.

A still further object of the invention is to generally improve the construction of a machine of this kind, the minor objects which are attained appearing from the following description of the device illustrated in the accompanying drawings. y

In said drawings :Fignre 1 is a side elevation. Fig. 2 is a plan view. Fig. 3 is an elevation taken from the side of the machine opposite to that of Fig. 1. Fig. 1 is a detail perspective view of: the cam-operated lever; Fig. 5 is a detail perspective view of the board feeding slide member. Fig. 6 is a detail perspective view of'the mechanism for maintaining the shooks'in position to'be fed to the box making machine. Fig. 7. is an enlarged detail sectional view of the abutment plate employed.

Referring to the drawings, 1 designates a suitable frame which is preferably constructed of wood and which is of such shape as to support the various elements heroin after specified. The numeral 2 designates the bed or table upon which the boards or shooks to be fed to the box making machine, are placed.

The parts of the machine are driven from a shaft 3 suitably mounted as in bearings 1. The shaft 3 is provided with a pulley 5 adapted to be engaged by a drivenbelt to or other impart motion to the shaft 3. The shaft 3' has slidably. secured thereon to revolve therewith, a friction wheel (imounted between the arms of a bracket 7, also slidable' along the shaft. Said bracket is provided with a plate 8 having a. screw threaded opening therein, which is engaged by a screw threaded portion of a rod 9 operated by means of a hand wheel 10. l

The wheel 6 frictionally engages and drives a plate or disk 11 on which is formed a suitable form of cam 12. The plate 11 and supported cam 12 are fixed to a vertical shaft 13 suitably mounted in bearings 14E on the frame 1. i

The numeral 15 designates a lever which is pivotedat 16 to the'frame 1, and has approximately midway of itsv length, a roller or wheel 16 pivoted at 17 to the lever 15 and an attaching arm 18 thereon, as best shown in Fig. 4. Said lever'at one end, is

deflected upwardly at 19 to raise a portion the outermost arc that may be described from the axis of the block so that the block maybe adjusted to different extents of projection toward the feed table, so as tofeed boards or shooksof different thicknesses or a plurality of boards or 'shooks simultaneously. The rod 23 passes through and is guided in a bracket 27 secured to the feeding table or other suitable part. To the rod 23 is adjustably secured a block or ring 28 by means of a set screw 29. A coil spring 30 is attached to said block 28 and to a suitable part of the machine, as at 31, which spring normally maintains the roller 16' in engagement with the cam.

The numeral 36 designates a bracket which may be suitably supported on the machine, and 37 designates a plate which is adjustable to extend beyond the inner face of the slide 23,.as by means of a screw 38engaging a threaded opening in the bracket and secured to the plate 37 so asto turn therein without disengagement therefrom. The plate 37 is also provided with addi; tional adjustment means consisting of screws 39 which are also screw threaded and.en

gage openings'provided in the bracket arm- .Said screws 39 merely bear against theplate 37 and serve as a support therefor in addition to the screw or bolt 38.

Along one side of the bed or table 2 is secured a board or bracket 40 which is slotted so as to slidably receive a plate or arm 41,

passage of but a single feed of boards or shooks therethrough at a time- The shooks or boards are placed upon the table or bed 2 with their sides parallel with the inner face of the slide 23, and the adjacent board or shook abuts or engages against the block 25. The adjustable feature of the block permits the accommodation of boards or shooks of different lengths, and the machine is adjusted to accommodate different thicknesses of board by means of the block 25 and adjustable plate 37 which may be projected beyond the inner face of the slide 23 so as to insure the feed of a single board in cases where the boards are of less thickness than the thickness of the block 25. There the boards are of greater thickness or equal thickness to the block 25, the machine may be adjusted to accommodate the passage of a single one of such boards or shooks by the adjustment of the plate 41.

The boards or shocks are held in vertical position and against the inner face of the plate 37, by means of a rod 44 which may be curved if desired, or of any other shape, and which is preferably provided with an upturned shook or board engaging end, as shown. The rod 44 is provided with 7 a handle 45 and is pivotally secured as shown, on a vertical rod 46 slidable on the rod 47 which is pivoted in blocks or supports 48. The rod 46 is slidable along the rod 47 so that the rod 44 may be brought centrally of the boardsor shooks A pedal or foot operable member 49 is secured to the rod 47, preferably slidably. Said slidable parts 46 and 49 are connected so as to turn with the rod 47 by means of a spline 50. A weight member 51 is provided on an arm 51* which is rigidly secured to the rod 47. The weight 51 is slidable on the arm 51 and is secured thereto by a set screw 51*, which permits adjustment of the weight to vary the tension on the rod 44. As the boards are fed from the bed or table, the rod 45 is moved inwardly and automatically through the fall- .ing or lowering of weight 51, to an extent equal to that left by the fed board or boards by means of the weight 51. But it is usual,

however,.to place a supply or quantity of boards upon the curved part of rod 44 and 'hold them thereon by hand, and as the supply against which the end of the rod 44 bears diminishes, the rod is pulled away from said diminishing supply and another supply is shoved off of the curved rod by hand, and the rod then allowed to return to position with its upturned end bearing against the supply of boards being fed. l/Vhen it is desired to supply the shooks or boards to the table or bed, or to remove the rod 44 from pressing against the boards or shooks, the pedal 49 is depressed whereupon the rod 44 will be raised. Upon releasing the pedal 49, the weight 51 restores the rod 44 to engagement with the boards or shooks. A guard rod or the like 52 is adjustably supported in a slot in a bracket 53, by means of a set screw 54, This guard rod 52 at one end, as seen in Fig. 2, bears against the shock or board next to the shook or board being fed and prevents the displacement of said next shook upon return movement of the rod 23 and block 25. In the absence of such rod 52, the frictional engagement of the block 25 with the said next shook would be sufficient, in some cases, to move the shook inwardly with the rod 52 upon its return movement.

The feeding of the boards is accomplished as follows, after the several parts described have been adjusted according to the length andthickness of thev boards. The disk or plate 11 is driven by frictional engagement with the wheel 6 and the speed of the wheel may be regulated by the distance of the wheel 6 from the shaft 13 as a center, the

wheel being adjusted through the rod 9 and co5perating parts. Upon the turning or r0- tation of the plate 11, the cam 12 is likewise rotated and periodically forces the roller 16 and attached lever 15 away from the same so as to reciprocate the rod 23.. Said rod 23 feeds a board or shook or a predetermined number of them, upon each reciprocation,

the block 25 engaging the boards or shooks tion. Upon the return movement of the rod 23 and block 25 the guard member 52 prevents the adjacent boards or shooks from being moved inwardly out of position.

The reciprocating rod and turnable block 25 enable the machine to operate effectively in connection with a special sawing process as follows.

Boards or shooks of the same thickness are first sawed into two boards, one of the sawed boards being one-half the thickness of the other sawed board. Such sawed boards are subsequently returned to the table 2 for further feeding and sawing, this time two boards, one of each of the two thicknesses, simultaneously upon each reciprocation of rod 23. According to the process the sawed boards of less thickness, when two sawed boards are fed simultaneously engages the plate 87 and thus in order to feed the two boards simultaneously the block or article-engaging member must be of such size as to extend completely across the adjacent end of one sawed board and partly across the adjacent end of the other sawed board without engagement with the third board from the plate 37. In order that a single block 25 may be used to feed single boards as first suggested and in order to feed two boards simultaneously, such block must be turnably mounted on the rod 28. The special process referred to is practised in connection with a special type of sawing machine unnecessary to particularl describe or illustrate as it forms no'part o the present invention.

My invention is not limited in its application to the feeding of boards or shooks as described, but may be used in other arts to feed other material, and it is to be understood also that changes within'the spirit and scope of the'appended claims may be made.

Having thus described'my' said invention, what I claim and desire to secure by Letters Patent is l. A reciprocating feed mechanism comprising a reciprocating member, an articleengaging member longitudinally adjustable, mounted oif center and turnable on said re ciprocating member to different degrees of projection on the feed side for engaging articles of different thickness.

2. A feed mechanism comprising a feed member movable relative to articles to be fed, an article-engaging member longitudinally adjustable, mounted 01f center and turnable on said reciprocating member to difierent degrees of projection on the feed side for engaging articles of difi'erent thickness, and means to fasten the article-engaging member to the feed member.
